Filter by:The purpose of this study is to evaluate the effectiveness and mechanism of action of Losartan in the treatment of coarctation of aorta.
The goal of this observational study is to determine the feasibility of renal Near Infrared Spectroscopy (NIRS) monitoring in the newborn nursery for newborns at low risk of coarctation of the aorta (CoA). The main questions it aims to answer are: - whether continuous renal NIRS monitoring is feasible; - whether NIRS monitoring results in higher nursing and parent/caregiver satisfaction than current standard monitoring; and, - whether participants who develop CoA will spend a smaller proportion of time within the normal range than patients who do not have CoA. Participants will be observed through continuous renal oxygenation monitoring with NIRS.
Coarctation of the aorta accounts for 4-7% of all congenital heart disease. While stent therapy, when feasible, is the standard of care for coarctation, it may not completely improve the work (and afterload) of the heart due to its effects on the elasticity of the aorta. This study will provide the information needed to understand the effects of current management on the cardiac mechanics and work.
The CT-Coarct-PED study is a multicentred observational study aiming to describe the population of early coarctation during the last 10 years in South of France. The secondary objective is to assess the importance of cross-sectional imaging in the surgical management of aortic coarctation in the first year of life
The study will include 40 patients who fulfil all the points in the inclusion and exclusion criteria will be randomized into two equal groups, each consisting of 20 patients, namely group (B) and group (C). - Group (B): will receive erector spinae plane block. - Group (C): will not receive any block. Postoperative pain score will be assessed using the FLACC scale or Face, Legs, Activity, Cry, Consolability scale immediately after extubation and at 1, 2, 4, 6, 8, 12, 18, and 24 hours. Routine postoperative analgesia in the form of intravenous paracetamol 7.5 mg/kg/6 hours will be given to all patients (the first dose is given after skin closure). Rescue analgesia in the form of 1 ug/kg fentanyl intravenously for patients if FLACC scale > 4, and the time for the first rescue analgesic administration will be recorded.
Neonatal patients with congenital heart defects (CHD) have changing physiology in the context of transitional period. Patients with CHD are at risk of low perfusion status or abnormal pulmonary blood flow. Near infrared spectroscopy has been used in neonatal intensive care units (NICU) to measure end-organ perfusion. The investigator plan on monitoring newborns with CHD admitted to the NICU with NIRS and echocardiography during the first week of life and correlate measures of perfusion from Dopplers to cerebral and renal NIRS.
This is a systemic research of Chinese aortic coarctation patients, aiming to determine risk factors and serial biomarkers of aortic coarctation in prognosis.
Hypoplastic aortic arch is a congenital heart defect that is prejudicial for the growth of newborns. It is often associated to other heart defects. Different surgical techniques exist to address this defect, but the literature is very poor with regards to the use of an autologous pericardial patch. Most use extensive dissection techniques or synthetic patches. Here investigators report institution's original approach using the newborns own pericardium for what investigators believe to be an optimal correction of the hypoplasia., with preserved growth potential.
Background: Coarctation of the aorta (CoA) can be treated using surgery, balloon angioplasty or stent implantation. Although short-term results are excellent with all three treatment modalities, long term cardiovascular (CV) morbidity and mortality remain high, likely due to persistently abnormal vascular function. The effects of treatment modality on long term vascular function remain uncharacterized. The goal of this study is to assess vascular function in this patient population for comparison among the treatment modalities. Methods: Vascular function in large and small arteries will be prospectively assessed fusing multiple non-invasive modalities, and the results will be compared among the three groups of CoA patients previously treated using surgery, balloon angioplasty or stent implantation after frequency matching for confounding variables. A comprehensive vascular function assessment protocol was created to be used in 7 centers. The primary outcome is arterial stiffness measured by arterial tonometry. Inclusion and exclusion criteria were carefully established after consideration of several potential confounders. Sample size was calculated for the primary outcome variable. Conclusions: Treatment modalities for CoA may have distinct impact on large and small arterial vascular function. The results of this study will help identify the treatment modality that is associated with the most optimal level of vascular function, which, in the long term may reduce CV risk.
